Environmental Information

The Metropolitan Washington Airports Authority (MWAA) conducts a wide variety of environmental studies to identify potential environmental impacts associated with proposed development projects. These studies are done in accordance with the National Environmental Policy Act (NEPA) of 1969, the regulations of the President's Council on Environmental Quality (CEQ) for NEPA compliance, and Federal Aviation Administration (FAA) Orders 1050.1F and 5050.4B.

Because NEPA is a federal law, compliance with NEPA is ultimately the responsibility of the FAA. However, as the project sponsor, MWAA is responsible for identifying the need for the proposed action, developing alternatives, and preparing the environmental documentation for FAA approval.
